All I get is: overlayfs: filesystem of lowerdir is not supported This is what I try: mount -t overlayfs -olowerdir=/etc,upperdir=/local/etc,workdir=/local/ovldir overlayfs /mnt /local is tmpfs in this case. If this is _not_ supposed to work I would strongly suggest, to clarify NFS support in Documentation/filesystems/overlayfs.txt Regards Sven -- "Das ist halt der Unterschied: Unix ist ein Betriebssystem mit Tradition, die anderen sind einfach von sich aus unlogisch."
